COMBINED COOKING-CAN AND DINNER-PAIL.

SPECIFICATION forming part of Letters Patent No. 230,274, dated July 20,1.880. Application filed February 11, 1880.

To altwhom it may concern:

Be it known that I, JOHN B. HAsKELL, of Staunton, in the county ofAugusta and State of Virginia, have invented a new Improvement inCombined Cooking-Gan and Dinner- Pail; and I do hereby declare that thefollowing is a full clear, and exact description of the same.

Myinvention is an improvement in the class of pails or cans which areconstructed with hollow walls or in part of some material which is a badconductor of heat for the purpose of preserving food for a considerabletime at a temperature which is either above or below that of thesurrounding atmosphere.

The improvement consists, first, in constructing the outer portion ofthecan or pail of gutta-percha or other suitable material, and a tin orother sheet-metal frame, which partly incloses and serves to protectit;second, in combining with such or equivalent outer portion of thecan orpail an inner can which is made of two separable parts and doublewalled, for the purpose of holding liquid and solid food. Such can isparticularly intended for holding hot coffee, soup, &c. It surrounds thechamber containing the solid food, and thereby aids in keeping warm, andeven in cooking, the latter. It therefore constitutes an importantfeature of my invention. y

In accompanying drawings, forming part of this specification, Figure lis a vertical oentral section, and Fig. 2 a side view, of my improvedpail. Fig. 3 is a vertical section of the inner can or receptacle forhot coffee or other liquid, the dotted lilies showing` its partsseparated. Fig. et is a vertical section of a modification;

The outer portion or cylinder A of my can or pail is constructed of oneor more sheets, a, of gutta-percha or otherlight material which is apoor conductor of heat, and of a tin or other sheet-metal frame, whichconsists, mainly, of the top and bottom 4rings b b and verticalconnecting-strips c. terials and the construction specified I secure thedesired qualities of lightness, durability, and non-conductivity.

The cover B of cylinder A is constructed of sheet metal or oth ersuitable material and provided with a lining, d, of felt or otherequiva- By such combination of maf lent substance.- The inner can, C,consists of two parts or cylinders, e j', which are separated at allpoints save at the top, where they are connected by means of a sort ofannular flan ged cap, g, which is an integral or permanent portion ofthe inner can, c, and lits closely over the edge of the outer can, f. Inother words, the inner'can, C, is hollow-walled; but its two partse fmay be easily detached from each other when required for the purpose ofcleaning them. The space h between the walls c f constitutes areceptacle for liquid, such as coffee, tea, or water, the same beingpoured in and discharged through an openingin the cap g, which` isprovided with a detachable plug, z'. Said can C is provided with acover, K, and contains a number of small trays or pans, Z, for holdingsolid food. These trays are placed one on another, and haveinwardly-projecting ears or handles m, to facilitate their removal. Thecan (l fits snugly into the cylinder u, ofnon-conducting material, whichis attached to or may form an integral portion of the outer pail or can,A-that is to say, the thick cylinder n, of non-conducting material, maybe formed in -one piece with the sheets a of guttapercha, or separatetherefrom, as desired; but when made separate they will be suitablyattached to each other.

lt is obvious that the outer part or cylinder, A, will preserve thetemperature of the contents of the inner or hollow-walled can, O, for along time, by reason of its incapacity for conducting heat rapidly and,further, that the space la between the walls ej" of such inner can, U,affords an additional barrier to passage of heat inward or outward. If,for example, such space h be filled with hot liquid, and solid food beplaced in a hot state in the trays l, said food will be kept hot for along time. Contrariwise, if the space h be lled with cool liquid, or,better still, with crushed ice, the

contents of vessel c will be kept at a low temperature for acorresponding period.

The chief use to which I propose to devote my invention is a dinnercooking-pail for workmen and others who require to take meals away fromhome. In such case the trays l will be filled with meat, vegetables,&c., which may be but partly cooked, and the hollow wall of the can Cfilled with hot coffee. It' this be IOO done, say at six a. m., theWorkman will nd at noon that the solid food is hot and completelycooked, and the coffee also as warm as required for drinking. Thus he isprovided with a warm dinner without any trouble or expense, and time iseconomized in preparing it in the morning, since it does not require tobe eompletely cooked at that time. y

Another use to which the invention may be applied is as a case fortmnsportingg` fruit, 85e. It', for example, baskets of strawberries besubstituted for the trays l, and pounded ice or even cold water beplaced in the receptacle c,

then the fruit will be kept in a cool state for alongtime, so as bedelivered in good comlition nt the end ot' a long trip in summer-time.

The use of the can for shipping ice-cream is another example of itsutility.

lt may also be employed for transporting and preserving temperature ofcream, beer, die.

I am aware the outer portion of a pail has been formed oi' gntta-perchaor other poor conductor of heat `and bound or incased in sheet metal attop and bottom. Such construction I do not claim.

l. The combination of the sheet-metal frame l formed of the two annularparts b b and the vertical strips c, which connect them with thegutta-percha part a., as shown and described.

2. The combination of the inner can orliquid-receptacle, C, having ahollow annular body provided with the valved opening in its top, and theouter portion or cylinder, A, formed of gutta-percha, and an inclosingor projecting metal frame, all as shown and described, for the purposespecified.

3. The can C, formed of the outer cylinder, f, and the inner cylinder,e, having,` a fianged cap, which tits closely on p21-rtf, but isdetachable therefrom, as shown and described,
